Searching content associated with multiple applications

ABSTRACT

Disclosed are examples of searching for content associated with multiple applications. In various examples, a first application can obtain a search query and maintain a list of applications available to provide content. The first application can send a request to a second application identified in the list, the request including a key that indicates the first application is authorized to request the second application to search for content. The first application can obtain a search result from the second application based on the request and present the search result in a user interface in the first application.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of and claims priority to application Ser. No. 14/968,914, filed on Dec. 15, 2015 and titled “SEARCHING CONTENT ASSOCIATED WITH MULTIPLE APPLICATIONS,” which is incorporated by reference herein in its entirety.

BACKGROUND

Users of computing devices often use applications to process and store data files that can include various types of content. For example, a user can use a word processing application to create, edit, and store word processing documents. When the user wants to view or edit the content in the word processing document, the user can operate the word processing application to open the file and render the content.

Over time, a user can store a large quantity of files. Eventually, it can become difficult for the user to locate a particular file due to the large quantity of files that a user can accumulate. In addition, it is common for multiple users to store files in the same storage system so that each user has access to all of the files in the storage system. However, the number of files stored by the multiple users can make it difficult for one user to find and access a particular file.

Search engines can facilitate a user finding files that match search queries. However, search engines often do not have the ability to search for content that is restricted from access for various reasons.

DETAILED DESCRIPTION

The present disclosure relates to the searching of content associated with applications in a client device. According to various examples, a search requester component of an application can request other applications in the client device to perform a search for content that matches a particular search query. After verifying that the application is authorized to request the search, search provider components in the other applications can search for content that matches the search query and provide the search requester with search results. Once the application receives the search results from the search providers, the application can render the search results in a user interface.

In the following discussion, examples of systems and their components are described, followed by examples of the operation of those systems.

With reference to FIG. 1, shown is an example of a networked environment 100. The networked environment 100 can include a computing environment 103 and a client device 106 in data communication through a network 109. The network 109 can include the Internet, one or more intranets, extranets, wide area networks (WANs), local area networks (LANs), wired networks, wireless networks, or any combination of two or more such networks. The network 109 can include satellite networks, cable networks, Ethernet networks, cellular networks, and telephony networks.

The computing environment 103 can be a computing environment operated by one or more enterprises, such as a business or other organization. The computing environment 103 can include a computing device, such as a server computer, that can provide computing capabilities. Alternatively, the computing environment 103 can include multiple computing devices arranged in one or more server banks or computer banks. For examples in which the computing environment 103 includes multiple computing devices, the computing devices can be located in a single installation, or the computing devices can be distributed among multiple different geographical locations.

In some examples, the computing environment 103 can include computing devices that together form a hosted computing resource or a grid computing resource. In other examples, the computing environment 103 can operate as an elastic computing resource for which the allotted capacity of computing-related resources, such as processing resources, network resources, and storage resources, can vary over time. In other examples, the computing environment 103 can include or be operated as one or more virtualized computer instances that can be executed in order to perform the functionality that is described herein.

The computing environment 103 can include various systems. For example, the computing environment 103 can include a management service 113 that can monitor and manage the operation of client devices 106 associated with the enterprise that operates the computing environment 103. In some examples, the management service 113 can manage and oversee the operation of multiple client devices 106 enrolled in a mobile device management service that is provided by the management service 113. The management service 113 can also provide the client devices 106 with access to email, calendar data, contact information, and other resources associated with the enterprise.

The management service 113 can assign various compliance rules 116 to respective client devices 106. The compliance rules 116 can specify, for example, one or more conditions that must be satisfied for a respective client device 106 to be deemed compliant with the compliance rule. In one example, a compliance rule 116 can specify that particular applications are prohibited from being installed in a client device 106. In another example, a compliance rule 116 can specify that a lock screen is required to be generated when the client device 106 is “awoken” from a low power “sleep” state and that a passcode is required for a user to unlock the lock screen. Some compliance rules 116 can be based on time, geographical location, or network properties. For instance, a client device 106 can satisfy a compliance rule 116 when a client device 106 is located within a particular geographic location.

A client device 106 can satisfy a compliance rule 116 in another example when the client device 106 is in communication with a particular network 109, such as a particular local area network that is managed by the computing environment 103. Furthermore, a compliance rule 116 in another example can be satisfied upon the time and date matching specified values.

Another example of a compliance rule 116 involves whether a user belongs to a particular group of authorized users. A compliance rule 116 can include a whitelist or a blacklist that specifies whether particular users or groups of users are authorized users. In various examples, the computing environment 103, the client device 106, or a combination of both the computing environment 103 and the client device 106 can determine whether a client device 106 satisfies a compliance rule 116.

In some examples, an enterprise can operate the management service 113 to ensure that the client devices 106 of its users satisfy respective compliance rules 116. By ensuring that the client devices 106 of its users are operating in compliance with the compliance rules 116, the enterprise can control access to resources to thereby improve the security of devices associated with the enterprise and the users of the client devices 106.

The computing environment 103 can also include an enterprise data store 119. The enterprise data store 119 can be representative of multiple enterprise data stores 119 accessible by components in the computing environment 103. The enterprise data store 119 can store various data associated with the computing environment 103. For example, the enterprise data store 119 can store the compliance rules 116 that the management service 113 has assigned to the respective client devices 106.

The enterprise data store 119 can also store developer resources 123. A developer resource 123 can be a resource that the management service 113 provides to developers, including third party developers, that can create and manage applications for client devices 106. Developer resources 123 can include libraries, such as security libraries and search libraries, that developers can incorporate into applications.

Developers can incorporate libraries into applications in various ways. For some examples, the management service 113 can provide a software development kit (SDK) to developers. Using the SDK, application developers can modify the source code of their applications to include the security libraries that are provided by the SDK.

In another approach, developers or the management service 113 can incorporate libraries into applications through a process known as “wrapping.” To wrap an application, the developer or management service 113 can decompile the application and then insert the libraries into the decompiled application. The developer or management service 113 can then compile the application with the added security libraries.

When a library is incorporated into an application using, for example, the SDK or application wrapping approaches described above, the functionality provided by the library can be invoked by the application when the application is executed in a client device 106. For example, if a security library provides functionality involving the ability to monitor activity in a client device 106 and enforce compliance rules 116, the application can call functions provided by the library to implement the activity monitoring and compliance rule 116 enforcement.

The client device 106 is representative of multiple client devices 106 that can be coupled to the network 109. The client device 106 can include a processor-based computer system, such as a desktop computer, a laptop computer, a personal digital assistant, a mobile phone, or a tablet computer. The client device 106 can include output devices, such as a display and audio speakers, as well as one or more input devices, such as a mouse, keyboard, touch pad, or touch screen, which can facilitate a user interacting with and controlling the client device 106.

The client device 106 can also include a first application 126 a, a second application 126 b, and a third application 126 c (collectively, the “applications 126”). Although the example depicted in FIG. 1 includes three applications 126, alternative examples can include fewer or greater numbers of applications 126. Each application 126 can include a set of computer programs that can perform various functionality. As one example, the first application 126 a can include a word processing application, the second application 126 b can include a media player that can render multimedia, and the third application 126 c can include an email client that can send and receive email messages. The applications 126 can be secured applications. In this regard, enterprise security libraries can be included in the applications 126, and the management service 113 can monitor and control the applications 126. For example, an application 126 can call functions provided by the security library to monitor or control activity associated with the application 126. In addition, the applications 126 can be signed with the same certificate key, which can facilitate interaction of the applications 126 with each other, as will be described in further detail below. Signing an application 126 with a certificate key can ensure that the application 126 has been developed by a trusted developer.

The applications 126 can be associated with first application content 129 a, second application content 129 b, and third application content 129 c (collectively, the “application content 129”) that is stored in a client data store 133. The application content 129 can include files and other types of data that the corresponding application 126 can access and process. The first application 126 a can access and process the first application content 129 a, the second application 126 b can access and process the second application content 129 b, and the third application 126 c can access and process the third application content 129 c.

The application content 129 can be associated with corresponding application content indexes 136 a-136 c (collectively, the “application content indexes 136”). The application content indexes 136 a can be regarded as search indexes that components can search to identify application content 129 that matches to a particular search query. By including the application content indexes 136, searches can be performed faster than if the actual application content 129 were searched instead.

The applications 126 can include various components. For example, the applications 126 can include corresponding search components 139 a-139 c (collectively, the “search components 139”). In some examples, developers can incorporate the search components 139 into applications 126 using an SDK or wrapping process, as described above. As will be described in further detail below, the search components 139 can facilitate a search for application content 129 being performed across multiple applications 126. To this end, the search components 139 can include corresponding search providers 143 a-143 c (collectively, the “search providers 143”) and search requesters 146 a-146 c (collectively, the “search requesters 146”). The search requester 146 of a particular application 126 can communicate with the search provider 143 of other applications 126. The search requester 146 can also request the search providers of other applications 126 to provide search results in response to search queries. As will be described in further detail below, the search providers 143 can receive search requests, generate corresponding search results, and provide the search results to the search requester 146 that requested the search.

The search components 139 can also include corresponding user interface controllers 149 a-149 c (collectively, the “user interface controllers 149”) and crawlers 153 a-153 c (collectively, the “crawlers 153”). The user interface controllers 149 can generate and control user interfaces for the corresponding application 126 to facilitate a user inputting search queries. The user interface controllers 149 can also render search results in user interfaces.

The crawlers 153 can parse application content 129 and update the application content indexes 136. In some examples, a crawler 153 can periodically parse the application content 129 and update the application content indexes 136. In other examples, the crawlers 153 can parse and update an application content index 136 in response to various triggers. For example, a trigger can be the current time matching a specified time. As another example, a trigger can be the detection of new application content 129 being stored in the client data store 133.

The client device 106 can also include an operating system that can create sandboxes 156 a-156 c (collectively, the sandboxes 156) for the respective applications 126. The sandboxes 156 can be regarded as being virtual containers for the respective applications 126 and associated resources. The sandboxes 156 can isolate resources, such as code and the application content 129, for the respective applications 126. For example, the sandbox 156 a can isolate the first application content 129 a so that only the first application 126 a can retrieve the first application content 129 a from the client data store 133. Accordingly, the first application 126 a can access the first application content 129 a from the client data store 133, but the second application 126 b, and the third application 126 c cannot retrieve the first application content 129 a from the client data store 133.

The operating system can also restrict the transfer of at least some types of data between components in the client device 106 based on various protection models. In some examples, the operating system can enforce a signature-based protection model. If a component is protected using the signature-based protection model, the operating system can allow the component to transfer data to only other components that are signed with the same certificate key. Thus, if a component subject to the signature-based protection model is signed with a certificate key that differs from another component, the operating system of the client device 106 can prohibit the component from sharing at least some data with the other component. In some examples, the applications 126 are signed with the same certificate key. Accordingly, the operating system can allow the applications 126 to transfer data, such as application content 129, between each other.

Next, examples of the operation of the networked environment 100 are described. To begin, the applications 126 installed in the client device 106 can maintain a list of the other applications 126 that are installed in the client device 106. To this end, in some examples, when an application 126 is installed in the client device 106, the newly installed application 126 can broadcast messages to the other applications 126 notifying the other applications 126 of the installation. Similarly, when an application 126 is being uninstalled in the client device 106, the application 126 being uninstalled can broadcast messages to the other applications 126 notifying the other applications 126 of the uninstallation. In alternative examples, the management service 113 can monitor the applications 126 being installed or uninstalled in the client device 106 and notify the applications 126 installed in the client device 106 when an additional application 126 is installed or when an existing application 126 is uninstalled. Thus, the applications 126 can store a list of other applications 126 that are in the client device 106.

As the client device 106 operates, the applications 126 can store various application content 129 in the client data store 133. For example, the first application 126 a can store first application content 129 a that includes word processing documents, the second application 126 b can store second application content 129 b that includes multimedia files, and the third application 126 c can store third application content 129 c that includes email messages. The application content 129 can be stored in the client data store 133 and isolated from various components in the client device 106 by virtue of the sandboxes 156 that are established by the operating system.

From time to time, the crawlers 153 of the search components 139 can parse the stored application content 129 to populate and update the respective application content indexes 136. In some examples, the crawlers 153 can begin this process periodically. In other examples, the crawlers 153 can populate and update the application content indexes 136 in response to various triggers, such as a new file being stored in the client data store 133. Accordingly, the crawlers 153 can generate and maintain the application content indexes 136, which can include entries that represent the corresponding application content 129.

As will now be discussed, the search components 139 of the applications 126 can be used to perform searches across the application content 129 of the multiple applications 126 installed in the client device 106. In the following discussion, the first application 126 a is being used to initiate a search, and the second application 126 b and third application 126 c provide the first application 126 a with search results. However, in alternative examples, the second application 126 b or third application 126 c can initiate a search and receive search results from the other applications 126 using the techniques described below.

To facilitate initiating a search, the user interface controller 149 a of the first application 126 a can generate user interface element, such as a text input box, that the user of the client device 106 can use to input a search query. The search query can include a text string in various examples. For instance, the user can input the text string of “accounting records” to search for information corresponding to accounting records that are associated with the applications 126.

In some examples, the user interface controller 149 a can include a user interface element that facilitates the user selecting particular categories of application content 129 and particular data fields to be searched. To this end, when an application 126 is installed in the client device 106, the newly installed application 126 or the management service 113 can notify the other applications 126 already installed in the client device 106 of the particular data fields that are searchable with respect to the corresponding application content 129. For instance, an email application 126 can notify other applications 126 that the email application 126 can search data fields specifying the sender of an email, the intended recipients of the email, the subject of an email, and various time stamps associated with the email. By the user interface controller 149 a providing a user interface element for the user to select particular categories of application content 129 or particular data fields to be searched, a user can limit the scope of a search.

Once a user has input a search query into the user interface generated by the user interface controller 149 a, the first search component 139 a can provide the search query to the search requester 146 a. Upon receiving the search query, the search requester 146 a can request the search components 139 b-139 c of the second application 126 b and the third application 126 c to search for second application content 129 b and third application content 129 c, respectively, that matches the search query. In some examples, the first search component 139 a can consult the list of installed applications 126 to identify the particular applications 126 the first search component 139 a should send a search request.

To request the search components 139 b-139 c to perform the search, the search requester 146 a can generate messages for the second application 126 b and the third application 126 c that make the requests. In particular, the messages for the second application 126 b and the third application 126 c can include payload data that represents the search query input by the user, the identity of the first application 126 a, a communication key that can indicate that the first application 126 a is authorized to request the search, the time the search is being requested, and the number of times the search has been requested by the first application 126 a. After the search requester 146 a has generated the messages, the search requester 146 a can provide the generated messages to the second search component 139 b and the third search component 139 c, respectively, using an interprocess communication service provided by the operating system of the client device 106.

When the second application 126 b receives the message from the search requester 146 a, the second application 126 b can extract the payload data and parse the contents of the payload data. In some examples, the second application 126 b can determine whether the received message includes a communication key indicating that the first application 126 a is authorized to communicate with the second application 126 b and request the second application 126 b to perform searches. In various embodiments, the second application 126 b can compare the received communication key with a stored value to determine whether the communication key is authentic. In other examples, the second application 126 b can request the management service 113 to determine whether the received communication key is authentic. If the communication key is not authentic, or if no communication key was received in the message, the second application 126 b can conclude that the message is from an unauthorized application and discard the message.

If the second application 126 b determines that the communication key is authentic, the second application 126 b can parse the payload of the received message to determine whether the message includes a request for a search to be performed. If the payload includes a request to perform a search, the second application 126 b can provide the extracted data to the search provider 143 b of the second search component 139 b. In some examples, the second application 126 b can determine whether to comply with the search. For example, the management service 113 or a user setting can instruct to second application 126 b to deny a search if a particular compliance rule 116 is not satisfied.

If the second application 126 b determines to allow a search to be performed, the search provider 143 b can extract the data representing the search query input by the user and perform a search based on the search query. In some examples, the search provider 143 b can search the second application content index 136 b to determine whether entries in the second application content index 136 b match the search query. In other examples, the search provider 143 b can search the second application content 129 b itself, including file names and metadata, to determine whether the content matches the search query. The search provider 143 b can perform search algorithms that search for synonyms and terms related to the search query.

If the search of the second application content 129 b or the second application content index 136 b indicates that files or other resources in the second application content 129 b match the search query, the search provider 143 b can collect information regarding the resources. For example, the search provider 143 b can include the name of the resource, a description of the resource, the storage location of the resource, the creator of the resource, and names of users who have accessed the resource. As will be described below, the search provider 143 b can provide this information to the search requester 146 a of the first application 126 a.

When the search provider 143 a has finished searching the second application content index 136 b or the second application content 129 b, the search provider 143 b can generate a message that represents the search results. In various examples, a search result can specify information associated with a resource that matches the search query, such as the name, a description, the storage location, the creator, and names of users who have accessed the resource. If no resources matched the search query, a search result can indicate that there were no resources in the second application content 129 b that match the search query.

The message that contains the search results can also include other information associated with the second application 126 b and the second application content 129 b. For example, the message can identify the second application 126 b so that the search requester 146 a of the first application 126 a can determine the source of the search results. In addition, the message can include a communication key that indicates that the second application 126 b is authorized to communicate with the first application 126 a. The message that contains the search results and potentially other information can be formatted in various ways. For instance, the message can be an extensible markup language (XML) file. In other examples, the message can be a JavaScript object notation (JSON) data object.

Once the search provider 143 b of the second application 126 b has generated the message containing the search results and potentially other information, the search provider 143 b can provide the message to the search requester 146 a of the first application 126 a. To this end, the search provider 143 b can use an interprocess communication service provided by the operating system of the client device 106.

As described above, the search requester 146 a of the first application 126 a can also send a message to the third application 126 c requesting the third search component 139 c to search for third application content 129 c that match the search query. The search provider 143 c can perform a search and provide a message to the search requester 146 a of the first application 126 a using the techniques described above. In some examples, the search provider 143 c of the third application 126 c can perform its search at the same time that the search provider 143 b of the second application 126 b performs its search. By the search providers 143 b-143 c performing their searches in parallel, the net time it takes to perform the searches may be less than if the searches were otherwise performed sequentially.

In addition to the search requester 146 a of the first application 126 a requesting the search providers 143 b-143 c of the second application 126 b and the third application 126 c to provide search results, the search requester 146 a of the first application 126 a can also request the search provider 143 a of the first application 126 a to search for first application content 129 a that matches the search query. The search provider 143 a can then search the first application content index 136 a or the actual first application content 129 a and generate search results using the techniques described above. The search provider 143 can then provide the search results to the search requested 146 a without using an interprocess communication service provided by the operating system of the client device 106.

Thus, as described above, the search requester 146 a of the first application 126 a can request the search providers 143 of the applications 126 to search for application content 129 that matches a search query that a user provided using the first application 126 a. Responsive to the requests, the search providers 143 can provide their respective search results.

Once the search requester 146 a obtains the search results from the search providers 143, the search requester 146 a can provide the search results to the user interface controller 149 a of the first application 126 a, and the user interface controller 149 a can render the search results in a user interface for the first application 126 a. The way in which the user interface controller 149 a presents the search results can vary according to various examples. In some examples, the user interface controller 149 a can order and present the rendered search results based on relevancy metrics. In another example, the user interface controller 149 a can group and present the rendered search results based on the identity of the application 126 that provided the respective search results. For example, search results from the first application 126 a can be presented in a first group, search results from the second application 126 b can be presented in a second group, and search results from the third application 126 c can be presented in a third group.

The user interface controller 149 a can also generate a user interface element that can facilitate a user of the client device 106 filtering or rearranging the rendered search results. For example, the user can specify that only search results from a particular application 126 should be rendered. As another example, the user can specify that the search results from a particular application 126 should be presented first in a user interface. In other examples, the user can filter search results based on various fields, such as fields specifying the type of application content 129 or creator of the application content 129.

In some examples, the user interface controller 149 a can include a user interface element that facilitates the user selecting whether to hide or not retrieve search results for application content 129 that is inaccessible due to a compliance rule 116 not being satisfied. In these examples, the applications 126 providing the search results can evaluate whether applicable compliance rules 116 are satisfied so that the corresponding application content 129 is accessible to the user. If an application determines that the application content 129 corresponding to a particular search result is not accessible, the user interface controller 149 a can omit the search result from the search results presented in a user interface. In other examples, the search providers 143 can provide search results to the search requester 146 a for only application content 136 that is accessible to the user.

When search results are rendered in a user interface, the user of the client device 106 can select a search result, and the user interface controller 149 a can perform various actions in response to the selection. In one example, the user interface controller 149 a can instruct the first application 126 a to retrieve and open the application content 129 that corresponds to the selected search result. In other examples, the user interface controller 149 a can identify the application 126 that provided the selected search result and instruct the identified application 126 to retrieve and open the application content 129 that corresponds to the selected search result. In addition, the user interface controller 149 a can cause the identified application 126 to become the primary active application 126 in the client device 106, so that the user does not have to manually cause the application 126 to become active. In another example, when the user selects a search result, the user interface controller 149 can designate the selected search result as a favorite search result and assign the search result to a list of favorite search results for later retrieval. In some examples, the user can request that the first search component 139 a forward the search result to another client device 106.

The particular actions that the user interface controller 149 a can perform with respect to search results can be specified by the applications 126 that provided the search results. For example, the search provider 143 of an application 126 that provides a search result can indicate actions that the operating system of the client device 106 can perform with respect to the search result as well as actions that the application 126 or other applications 126 can provide with respect to the search result. In some examples, the when a search requester 146 requests the search providers 143 to provide search results, the search requester 146 can also request the search providers 143 to specify the actions that the operating system and the applications 126 can perform with respect to the search result. In other examples, the search providers 143 can provide this information without an explicit request from the search requester 146. For example, a search provider 143 can specify that the operating system can cause a user interface for a particular application 126 to become the active foreground user interface so that application content 129 corresponding to a search result can be rendered in the user interface and presented to the user. As another example, the search provider 143 can specify that one or more particular applications 126 are capable of sharing the application content 129 corresponding to the search result to another client device 106.

In some examples, the user interface controller 149 a can render a list of options of actions that the user interface controller 149 a can take with respect to a search result. The user interface controller 149 a can render the list of options in response to a user interacting with the user interface in various ways. For instance, the user can press and hold a finger on a touchscreen over a rendering of a search result to prompt the user interface controller 149 a to display a list of actions that the user interface controller 149 a can perform with respect to the search result. In another example, the user interface controller 149 a can display the list of actions in response to a user performing a swipe gesture is association with the rendering of the search result.

With reference to FIG. 2, shown is a sequence diagram illustrating an example of interactions of components in the networked environment 100. The sequence diagram of FIG. 2 illustrates an example of the first search component 139 a of the first application 126 a obtaining search results that correspond to a search query and presenting the search results in a user interface.

Beginning with step 203, the first search component 139 a can obtain a search query. In some examples, the user interface controller 149 a can generate a user interface element, such as text box, that can facilitate a user of the client device 106 inputting the search query. The search query can include a text string in various examples. In addition, the user in some examples can select the particular applications 126 or categories of application content 129 for which the first search component 139 a can initiate a search.

The first search component 139 a can then move to step 206 and generate search results that match the search query. To this end, the search requester 146 a of the first search component 139 a can provide the search query to the search provider 143 a of the first search component 139 a. The search provider 143 a can then search the first application content 129 a or the first application content index 136 a for resources that match the search query. The search provider 143 a of the first search component 139 a can return a list of search results to the search requester 146 a of the first search component 139 a in the form of an XML file or JSON data object in various examples.

As shown at step 209, the first search component 139 a of the first application 126 a can send a request for search results to the second search component 139 b of the second application 126 b. In various embodiments, the search message can include payload data that represents the search query input by the user, the identity of the first application 126 a, a communication key that can indicate that the first application 126 a is authorized to request the search, the time the search is being requested, and the number of times the search has been requested by the first application 126 a.

At step 213, the second search component 139 b can generate search results representing second application content 129 b that matches the search query. It is noted that, in some examples, the second search component 139 b can generate the search results at the same time that the first search component 139 a and the second search component 139 b generate their search results at steps 206 and 213. To generate the search results, the search provider 143 c of the second search component 139 b can search the second application content 129 b or the second application content index 136 b for resources that match the search query. The second search component 139 b can then move to step 216 and send the generated search results to the first search component 139 a of the first application 126 a. The second search component 139 b can use an interprocess communication service provided by the operating system of the client device 106 to send search results in the form of an XML file or JSON data object in various examples.

As shown at step 219, the first search component 139 a of the first application 126 a can send a request for search results to the third search component 139 c of the third application 126 c. In various embodiments, the search request can include payload data that represents the search query input by the user, the identity of the first application 126 a, a communication key that can indicate that the first application 126 a is authorized to request the search, the time the search is being requested, and the number of times the search has been requested by the first application 126 a.

At step 223, the third search component 139 c can generate search results that represent third application content 129 c that matches the search query. It is noted that, in some examples, the third search component 139 c can generate the search results at the same time that the first search component 139 a and the second search component 139 b generate their search results at steps 206 and 213. To generate the search results, the search provider 143 c of the third search component 139 c can search the third application content 129 c or the third application content index 136 c for resources that match the search query. The third search component 139 c can then move to step 226 and send the generated search results to the first search component 139 a of the first application 126 a. The third search component 139 c can use an interprocess communication service provided by the operating system of the client device 106 to send search results in the form of an XML file or JSON data object.

At step 229, the first search component 139 a can present the search results generated by the first search component 139 a, the second search component 139 b, and the third search component 139 c in a user interface. In particular, the user interface controller 149 a of the first search component 139 a can render the search results. As described above, the user interface controller 149 a can also order the search results based on relevancy metrics or group the search results based on the identities of the applications 126 that provided the respective search results. Thereafter, the process can end.

With reference to FIGS. 3A-3B, shown is a flowchart that provides an example of a portion of the operation of the first search component 139 a. In particular, FIGS. 3A-3B provide an example of the first search component 139 a obtaining search results associated with the first application 126 a, the second application 126 b, and the third application 126 c. It is noted that the second search component 139 b and the third search component 139 c can operate in a similar manner as the first search component 139 a. The flowchart of FIGS. 3A-3B can be viewed as depicting an example of a method implemented in the client device 106.

Beginning with step 303, the first search component 139 a can obtain a search query. In various examples, the search query can include a text string that a user of the client device 106 has input into the client device 106. At step 306, the first search component 139 a can search the first application content index 136 a for entries that match the search query. For example, the first search component 139 a can identify entries that relate to the search entry using search algorithms. In alternative embodiments, the first search component 139 a can search the first application content 129 a seeking to identify resources that match the search query.

At step 309, the first search component 139 a can generate a message requesting the second application 126 b to search for second application content 129 b that matches the search query. As discussed above, the message generated by the first search component 139 a can include payload data that represents the search query input by the user, the identity of the first application 126 a, a communication key that can indicate that the first application 126 a is authorized to request the search, the time the search is being requested, and the number of times the search has been requested by the first application 126 a. As shown at step 313, the first search component 139 a can then provide the generated message to the second application 126 b. In some examples, the first search component 139 a can use an interprocess communication service provided by the operating system to send the message to the second application 126 b.

At step 316, the first search component 139 a can generate a message requesting the third application 126 c to search for third application content 129 c that matches the search query. As discussed above, the message generated by the first search component 139 a can include payload data that represents the search query input by the user, the identity of the first application 126 a, a communication key that can indicate that the first application 126 a is authorized to request the search, the time the search is being requested, and the number of times the search has been requested by the first application 126 a. As shown at step 319, the first search component 139 a can then provide the generated message to the third application 126 c. In some examples, the first search component 139 a can use an interprocess communication service provided by the operating system to send the message to the third application 126 c.

As indicated at step 323, the first search component 139 a can obtain search results from the second application 126 b and the third application 126 c. As described above, the search results can take the form of an XML file or a JSON data object in various examples.

As shown at step 326, which is in FIG. 3B, the first search component 139 a can present the obtained search results in a user interface. As discussed above, the first search component 139 a can also order the search components based on relevancy metrics or group the search results based on the particular application 126 to which the search result corresponds.

At step 329, the first search component 139 a can determine whether a user of the client device 106 selected a search result that is presented in the user interface. If a search result was not selected, the process can end as shown. Otherwise, if the user did select a search result, the first search component 139 a can identify the application 126 that provided the selected search result, as indicated at step 333. In some examples, the first search component 139 a can identify the application 126 because the application 126 can provide an identifier when providing the search result to the first search component 139 a.

At step 336, the first search component 139 a can generate a message requesting the identified application 126 to access the application content 129 that corresponds to the selected search result. The first search component 139 a can also request the identified application 126 to perform various actions with respect to the application content 129 that corresponds to the selected search result. For example, the first search component 139 a can request the identified application 126 to share the application content 129 with another device or to cause a user interface for the identified application 126 to become an active foreground user interface in which the application content 129 is rendered.

Then, at step 339, the first search component 139 a can provide the generated message to the identified application 126. For examples in which the identified application 126 is the second application 126 b or the third application 126 c, the first search component 139 a can send the message to the second application 126 b or the third application 126 c using the interprocess communication service provided by the operating system of the client device 106. For examples in which the identified application 126 is the first application 126 a, the first search component 139 a can provide the message to the first application 126 a without using interprocess communication techniques, because the first search component 139 a can be a component of the first application 126 a. Thereafter, the process can end.

With reference to FIG. 4, shown is a flowchart that provides an example of a portion of the operation of the second search component 139 b. In particular, FIG. 4 provides an example of the second search component 139 b responding to a request from the first search component 139 a to perform a search. It is noted that the first search component 139 a and the third search component 139 c can operate in a similar manner as the second search component 139 b. The flowchart of FIG. 4 can be viewed as depicting an example of a method implemented in the client device 106.

Beginning at step 403, the second search component 139 b can obtain a message from the first application 126 a requesting the second application 126 b to search for second application content 129 b that matches a search query. As discussed above, the message can include the search query as well as a communication key that indicates whether the first application 126 a is authorized to request the second search component 139 b to perform searches.

At step 406, the second search component 139 b can determine whether the first application 126 a is authorized to request the second search component 139 b to perform searches. In some examples, the second search component 139 b can compare the communication key contained in the message received at step 403 to a known value to determine whether the first application 126 a is authorized to request a search. In other examples, the second search component 139 b can maintain a list of applications 126 that are permitted to request searches. In an alternative example, the second search component 139 b can communicate with the management service 113, and the management service 113 can specify whether the first application 126 a is authorized to request a search.

If the first application 126 a is not authorized to request a search, the process can end as shown. Otherwise, if the second search component 139 b determines that the first application 126 a is authorized to request a search, the second search component 139 b can move to step 409 and search the second application content index 136 b for entries that match the search query. In other examples, the second search component 139 b can search the second application content 129 b for resources that match the search query.

After the search, the second search component 139 b can generate a message that includes the search results, as shown at step 413. In addition, the message can include information that identifies the second application 126 b, and time the search was performed. At step 416, the second search component 139 b can provide the generated message to the first application 126 a. In some examples, the second search component 139 b can use an interprocess communication service provided by the operating system to send the message to the first application 126 a. Thereafter, the process can end.

With reference to FIG. 5, shown is a flowchart that provides another example of a portion of the operation of the second search component 139 b. In particular, FIG. 5 provides an example of the second search component 139 b receiving and processing a request to perform an action with respect to second application content 129 b that corresponds to a search result. It is noted that the first search component 139 a and the third search component 139 c can operate in a similar manner as the second search component 139 b. The flowchart of FIG. 5 can be viewed as depicting an example of a method implemented in the client device 106.

Beginning with step 503, the second search component 139 b can obtain a message from the first application 126 a requesting the second application 126 b to perform an action with respect to second application content 129 b. The second application content 129 b can correspond to a search result that the second search component 139 b provided to the first application 126. Examples of requested actions include opening the second application content 129 b, sharing the second application content 129 b to another application 126 or device, and annotating the second application content 129 b

At step 506, the second search component 139 b can determine whether applicable compliance rules 116 are satisfied so that the second application 126 b is permitted to perform the requested action. If the applicable compliance rules 116 are not satisfied, the process can end, as shown. In addition, the second search component 139 b can perform a remedial action in response to the compliance rules 116 not being satisfied. For instance, the second search component 139 b can notify the user of the client device 106 or an administrator of the management service 113 of the non-compliance. As other examples, the second search component 139 b can modify a setting in the client device 106 so that the compliance rules 116 become satisfied.

If the applicable compliance rules 116 are satisfied, the second search component 139 b can proceed to step 503 and perform the requested action. For example, the second search component 139 b can cause the second application 126 b to open the second application content 129 b, share the second application content 129 b to another application 126 or device, or annotate the second application content 129 b, as requested by the first application 126 a. Thereafter, the process can end.
